Acceleration Converter (m/s², g, ft/s², Gal)
Convert acceleration between m/s², standard gravity (g), ft/s², and Gal (used in geophysics/seismology). Runs entirely in your browser.
How it works
Every unit is converted through a common base unit — meters per second squared. "g" here means standard gravity (9.80665 m/s²), the reference used to describe forces felt during acceleration (e.g. "3g in a fighter jet turn"), not the gram (a unit of mass).
Common conversions
| From | To | Result |
|---|---|---|
| 1 g | m/s² | 9.80665 m/s² |
| 0-100 km/h in 5s | g | ≈0.566 g (5.556 m/s² ÷ 9.807) |
| 1 m/s² | ft/s² | 3.2808 ft/s² |
| 1 Gal | m/s² | 0.01 m/s² |
FAQ
What does "3g" mean?
Three times the acceleration due to standard gravity — about 29.42 m/s². It's a common way to describe forces felt during rapid acceleration, braking, or turning.
What is a Gal?
A centimeter per second squared (0.01 m/s²) — a small unit used mainly in geophysics and seismology to measure ground acceleration during earthquakes.
